STF6NK70Z - N-channel 700 V, 1.25 Ω, 5.4 A Zener-protected SuperMESH™ Power MOSFET in TO-220FP package
The STF6NK70Z is a high-performance N-channel Power MOSFET produced using STMicroelectronics' innovative SuperMESH™ technology, which combines the benefits of reduced on-resistance, Zener gate protection, and high dv/dt capability. This power MOSFET is designed to offer extremely high packing density for low on-resistance, rugged avalanche characteristics, and less critical alignment steps, therefore providing a superior manufacturing reliability and efficiency.
Key Features
- 100% avalanche tested
- Outstanding dv/dt capability
- Gate charge minimized
- Very low intrinsic capacitances
- Very good manufacturing repeatability
Applications
The STF6NK70Z is suitable for a variety of applications, including switch-mode power supplies (SMPS), high-efficiency DC-DC converters, and power management functions in both consumer and industrial electronics. Its robust design also makes it ideal for hard-switching environments and high-performance designs where reliability is key.
Electrical Characteristics
This MOSFET can handle continuous drain currents up to 5.4 A, with a maximum drain-source voltage (V<sub>DS) of 700 V. The threshold voltage (V<sub>GS(th)) ranges from 2.0 to 4.0 V, making it compatible with standard drive voltages. Its on-resistance (R<sub>DS(on)) is as low as 1.25 Ω, which contributes to its high efficiency in power conversion applications.
Package Details
The STF6NK70Z comes in a TO-220FP package, which is widely used and known for its good thermal performance. The TO-220FP package allows for efficient heat dissipation and easy mounting on heat sinks, which is crucial for maintaining the longevity and reliability of the device under high-power conditions.
